Vertical Sidewall Installations

Important! Minimum clearance between vent pipes and combustible materials is three (3") (76mm) on top, and (1") (25mm) on bottom

and sides.

Important! When vent termination exits through foundation less than 20" below siding outcrop, the vent pipe must ﬂush up with the

siding. SD-1284 or SD-985 termination cap must be used.

Information on Various Venting Routes and Components

Important: It is always best to locate the ﬁreplace in such a way that minimizes the number of offsets and horizontal vent length.

Since it is very important that the venting system maintain its balance between the combustion air intake and the ﬂue gas exhaust, certain

limitations as to vent conﬁgurations apply and must be strictly adhered to.

The graph showing the relationship between vertical and horizontal side wall venting will help to determine the various vent lengths

allowable.

The horizontal vent run refers to the total length of vent pipe from the ﬂue collar of the ﬁreplace to the face of the outer wall.

The maximum horizontal vent run is 20 feet (457 cm) when the vertical vent rise is 8 feet (244 cm). See Figure 17.

Venting terminals shall not be recessed into wall or siding.
